PRIORITY CLAIM

The present application is a non-provisional patent application, claiming the benefit of priority of U.S. Provisional Application No. 60/859,579, filed on Nov. 15, 2006, titled, “Connectable blocks.”

BACKGROUND OF THE INVENTION

(1) Field of Invention

The present invention relates to stackable blocks and, more particularly, to a collection of connectable blocks that are made of a foam material and that can be stacked and/or connected to form a variety of shapes.

(2) Description of Related Art

Stackable blocks have long been known in the art. As an improvement over simple stackable blocks, Lego™ blocks were conceived that are connectable using male and female corresponding parts. Lego™ blocks are produced by the Lego Company, located at DK-7190 Billund, Denmark. Such connectable blocks have long been used to create a variety of miniature configurations. A problem with existing blocks is that they are small and do not allow a user to easily build large creations. Another problem with existing blocks is that should a user decide to position a sticker or otherwise adhesive backed material to the blocks, they will likely stick permanently and cannot be easily removed.

Thus, a continuing need exists for large, connectable blocks that allow a user to easily attach and detach adhesive backed items.

(1) Description

The present invention relates to connectable blocks 100. The top-side perspective, bottom-side perspective, top-orthogonal and bottom-orthogonal views of a connectable block are shown in FIG. 1A through FIG. 1D, respectively. The blocks include a frame 101 with both male 102 and corresponding female 104 parts that allow them to be connected with each other. For example, the male part 102 can be a raised circle-shape and the corresponding female part 104 can be a hollowed-out circle shape, as shown in FIGS. 1A and 1B. Although depicted as circle-shapes, as can be appreciated by one skilled in the art, the present invention is not intended to be limited thereto as there are numerous male and corresponding female shapes that allow for connection of two components.

As shown in FIG. 2, the male 102 and female 104 parts can also be interlocking Z-shapes, or any other shape in which the male 102 and female 104 parts can be attached and detached with one another and create stacked embodiments 200. Although depicted as interlocking blocks, one skilled in the art can appreciate that other shapes can be devised to accomplish the same purpose. As depicted in FIG. 2, the blocks are vertically and horizontally stackable blocks.

As shown in FIG. 3 and FIG. 4, a plurality of blocks 100 can be provided in a kit 110, where the kit 110 contains connectable blocks 100 of varying sizes. For example, single 112, double 114, and triple-sized 116 blocks can be provided, according to the number of male 102 and corresponding female 104 parts placed horizontally or vertically on each block. The blocks can also be provided in larger sizes, for example, a two-by-five block will have ten male 102 and ten corresponding female 104 parts. The larger-sized blocks can be used as bases to build upon.

Unlike existing and traditional stackable blocks, which are small and have smooth sides, the blocks 100 of the present invention are large and include surfaces 106 which are textured. The blocks 100 are made of any suitably durable and rigid material, non-limiting examples of which include expanded polypropylene (EPP) foam, and expanded polystyrene (EPS) foam. The blocks 100 can be formed in multiple colors and can be made of shiny or glittery materials. As shown in FIG. 5, the surfaces 106 are textured sufficiently to allow an adhesive-backed material 108 (such as a sticker) to be detachably attachable with the blocks 100. In other words, the surfaces 106 are textured (as a textured surface) to reduce the contact points between the block 100 and an attached material 108. By reducing the contact points, the adhesive-backed materials 108 can be easily attached and removed, thereby allowing a user to easily replace the adhesive-backed material 108 with another adhesive-backed material 108. As can be appreciated by one skilled in the art, the surfaces 106 includes any suitable texture for reducing the contact points. In other word, the surfaces 106 are not completely flat such that there are a plurality of protrusions and recessions, with the protrusions providing the contact points 109 along a plane 111 that lies upon the surface 106 (the plane 111 is depicted as being removed from the surface 106 for illustrative purposes), a non-limiting example of which includes an indented grid pattern. A non-limiting example of such an indented grid pattern includes numerous pyramid-shaped protrusions 110. Each pyramid-shaped protrusion provides a contact point 112 at the tip of the pyramid-shaped protrusion that acts as the surface for attachment with the adhesive-backed material 108. The protrusions 110 can be equally spaced or formed at random locations. Further, the protrusions can be as few as three per side and up to millions per side. In a desirable aspect, there are between ten and a few thousand protrusions formed on the surface 106.

Additionally, the blocks 100 can be formed in different shapes and connect with each other to form different-shaped toys. For example, as shown in FIG. 6, the blocks 100 can be connected to form animal 600, truck 602, airplane 604 shapes. Other examples of shapes include train, spaceship, people, car and building shapes (not shown). The blocks 100 can be packaged in a kit so that all the blocks 100 necessary to form the shape are present.

As mentioned above, an adhesive-backed material 108 (such as a sticker) can be provided with the blocks to be detachably attached with the blocks to increase the aesthetic look of the blocks and enhance the image of the shape formed by the connected blocks. As shown in FIG. 7 and as a non-limiting example, when the blocks are connected to form the shape of a fire truck 700, stickers (i.e., adhesive-backed material 108) that portray parts of a fire truck can be provided. In this and other aspects, the surface of the blocks 100 can be textured (as described above) to reduce the number of contact points between the surface and the adhesive-backed material. Also, other materials can be included with the kit of blocks to add to the functionality of the blocks. For example, if a kit of blocks is packaged to create a fire truck shape, wheels 702 can be included in the package to detachably attach with a larger-sized base block, allowing the block stacked on the base to roll like a truck.

Additionally, the connectable blocks 100 can be formed to include a side with a surface that has an adhesive backing 802 formed on the surface. Thus, using the adhesive backing 802, the blocks can connect with another object 800, such as a wall, and the user can build shapes with the blocks off of that object. Such blocks can be attached to a wall (or stacked up) and extend out horizontally, as shown in FIG. 8. As can be appreciated by one skilled in the art, the adhesive backing 802 is any suitably adhesive material, non-limiting examples of which include glue and other sticky substances.

Further and as shown in FIG. 9, to facilitate stacking the blocks 100 on a wall 900, the blocks 100 can be formed to include male 102 and female 104 parts that provide support in both the horizontal 902 and vertical 904 directions, a non-limiting example of which includes the interlocking Z-shapes. Additionally, a wall mount 906 can be included that allows the blocks 100 to be attached with and hang from the wall mount 906. Due to the interlocking Z-shaped male 102 and female 104 parts, the blocks 100 can be extended horizontally from the wall mount 906 (which also includes Z-shaped male 908 and female 910 parts).

In summary, the present invention relates to connectable blocks 100 with male 102 and female 104 parts that allow for connection of the blocks 100. In some aspects, the blocks 100 include a textured surface to reduce the number of contact points between the blocks 100 and a detachably attachable adhesive-backed material. Additionally, the blocks 100 can be formed in a variety of shapes such that when connected, they collectively form different-shaped toys. Finally, in some aspects, the blocks 100 include male 102 and female 104 parts that provide support in both the horizontal 902 and vertical 904 directions.
